Question

y=13 is a solution to the inequality y+4<16

Answer 1

Answer:

No

Step-by-step explanation:

First subtract 16 from both sides

• y + 4 < 16
• y + 4 - 16 < 16 - 16
• y - 12 < 0                  
• So 0 has to be greater than whatever is on the left
• If y = 13 is put into the inequality you get 13 - 12 < 0.
• What is ultimately true is that 1 < 0
• Is 1 smaller than 0?
• No

13 is not a solution to the original inequality.
